Put the following into your /etc/asound.conf or ~/.asoundrc:

pcm.multi {
	type plug
	slave.pcm {
		type multi
		slaves.a {
			pcm "hw:0"
			channels 2
		}
		slaves.b {
			pcm "hw:1"
			channels 2
		}
		slaves.c {
			pcm "hw:2"
			channels 2
		}
		bindings [
			{ slave a channel 0 }
			{ slave a channel 1 }
			{ slave b channel 0 }
			{ slave b channel 1 }
			{ slave c channel 0 }
			{ slave c channel 1 }
		]
	}
}

and tell Jack to use device name "multi".
